    Dale od ni zajimave:

    A major cause of uncertainties in climate projections is our imprecise knowledge of how much warming should occur as a result of a given increase in the amount of carbon dioxide in the atmosphere. Paleoclimate records have the potential to help us sharpen that understanding because they record such a wide variety of environmental conditions. Tierney et al. review the recent advances in data collection, statistics, and modeling that might help us better understand how rising levels of atmospheric carbon dioxide will affect future climate.

    The Detection and Attribution of Northern Hemisphere Land Surface Warming (1850–2018) in Terms of Human and Natural Factors: Challenges of Inadequate Data
    Climate | Free Full-Text | The Detection and Attribution of Northern Hemisphere Land Surface Warming (1850–2018) in Terms of Human and Natural Factors: Challenges of Inadequate Data

    The IPCC AR6 concluded that “climate models can only reproduce the observed warming […] when including the effects of human activities […], in particular the increasing concentration of greenhouse gases”, and that “simulations that include only natural process, including internal variability related to El Niño and other similar variations, as well as variations in the activity of the sun and emissions from large volcanoes […], are not able to reproduce the observed warming” (AR6, FAQ 3.1, p. 515) [1]. Largely on this basis, AR6 concluded that contemporary climate change is “overwhelmingly due to human influence” (Technical Summary, p. 11). However, in this article, we argue that this confident “detection and attribution of climate change” statement was unjustified because it failed to satisfactorily assess two key ongoing scientific debates:

    1. How much of the warming since the 19th century implied by current global temperature estimates is an artifact of urbanization biases?
    2. Have we established a reliable solar forcing dataset for estimating the solar contribution to these trends?

    Empirical assessment of the role of the Sun in climate change using balanced multi-proxy solar records
    https://www.sciencedirect.com/science/article/pii/S1674987123001172

    • Factors other than direct TSI forcing account for around 80% of the solar influence on the climate.
    • Important solar-climate mechanisms to be investigated before developing reliable GCMs.


    ...empirical studies often found that the solar contribution to climate changes throughout the Holocene has been significant, whereas GCM-based studies, which only adopt radiative forcings, suggest that the Sun plays a relatively modest role.

    The CMIP6 GCMs appear to greatly underestimate the Sun’s role in climate change because of two major limitations: erroneous solar forcings have likely been integrated into the models; and TSI alone appears to likely be not the most important solar forcing. Additional solar-magnetism related forcings and associated mechanisms are not included in the GCMs because they are currently poorly understood, despite the fact that there are several empirical indications that they might sufficiently modulate the cloud cover system (by 5% or less) to explain a significant component of the observed climatic changes.

    At least about 80% of the solar influence on the climate could be generated by processes other than direct TSI forcing. If this result is correct, several solar-climate mechanisms must be thoroughly investigated and fully understood before reliable GCMs can be developed.

    Za dva biliony euro by Evropa mohla být zelená a energeticky nezávislá - Seznam Zprávy

    Europe could become energy self-sufficient in $2 trillion push, study says | Reuters
    https://www.reuters.com/markets/europe/europe-could-become-energy-self-sufficient-2-trillion-push-study-2023-10-04/

    The report, led by the Potsdam Institute for Climate Impact Research, said the continent would require annual investments of 140 billion euros by 2030 and 100 billion a year in the decade thereafter to get there.

    While most of the sum would be needed for onshore wind expansion, solar, hydrogen and geothermal resources would be additional pillars of a strategy that would enable Europe's electricity needs to be powered exclusively from renewables by 2030.

    It would take another decade to convert the entire energy system, including things such as heating currently powered by oil or gas, to renewables, according to the study, which was shared with Reuters.

    Dneska zamrzne peklo. Poprvé v životě jsem napsal pochvalný článek na ministra průmyslu a obchodu. Jozef Síkela se totiž v minulých týdnech postavil zájmům uhlobaronů a zejména vytáhl na světlo fakt, že Daniel Křetínský využívá svá média k politickému boji.

    degenerativni, male i velke farmy musi byt prekonany

    Co konkrétně vám na Green Dealu vadí?

    Je to celé o snižování výroby. Marie Terezie zrušila úhory (neudržovaný/neužívaný kus půdy, který se po nějaký čas nechává tzv. „ležet ladem“, pozn. red.), Zelený úděl je zavádí. Letos byly úhory povinné na 5 procentech jakékoliv půdy, příští rok to bude už 10 procent orné půdy. To je likvidace zemědělství. Až 30 procent produkčního zemědělství se má převést do ekologie. Dnes máme v ekologickém režimu 17,6 procenta půdy, tedy asi 600 tisíc hektarů z 3,5 milionu hektarů zemědělské půdy, ale s produkcí pouze 1,3 procenta. Na co berou téměř dvojnásobné dotace?

    Už osm let bojujeme proti uhelnému průmyslu v České republice. Za ty roky jsme přispěly*i k záchraně Horního Jiřetína, konci uhlí do roku 2033 a také se nám povedlo dostat klimatickou krizi do veřejné diskuze. Uhelný byznys, posilněný rekordními zisky z loňského roku, se však nechce jen tak vzdát. Od roku 2018 uhelné firmy šikanují lidi, kteří se rozhodly*i protestovat proti ničení planety i formou občanské neposlušnosti. Uhelné společnosti podávají zastrašující žaloby, kterými se snaží klimatické hnutí připravit o peníze a odradit ho od dalších aktivit. Abychom se proti útokům uhlobaronů mohly*i účinně bránit, potřebujeme pokrýt naše právní výdaje. Právě tady vstupuješ do hry ty! Od začátku jsme v tom společně, i pomoct si musíme navzájem.
